| molecularNote | CRISPR/Cas9 technology was used to generate two deletions in the promoter region. The first deletion, of 16 bp, encompasses base pairs -95 through -80 relative to the translation initiating ATG. The second deletion, of 649 bp, encompasses base pairs -809 through -160 relative to the ATG start codon. |
